PAPER CUTTING AND WINDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 610,329, datedSeptember 6, 1898.

Application filed August 27, 1897. Serial No. 649,778. (No model.)

To all whom it may concern:

Be it known that I, FRANCIS MEIsEL, a citi-.

zen of the United States, residing at Boston, in the county of Suffolkand State of Massachusetts, have invented certain Improvements inMachines for Cutting WVebs of Paper and \Vinding up the Same into Rolls,of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, making part of thisspecification, in which Figure 1 is an elevation of one side of myimproved paper cutting and winding machine. Fig. 2 is an elevation ofthe opposite side. Fig. 3 is a front elevation of the machine. Fig. 4 isa sectional detail of the clutch or friction pulley which is connectedwith the automatic stop-motion. Fig. ,5 is a diagram illustrating thecourse of the web of paper through the machine. Fig. 6 is a horizontalsection on the line 6 6 of Fig.3. Fig. 7 is a detail of a portion of thestop-motion. Fig. 8 is a side elevation of'one of the papercutting disksand the collar by means of which it is secured to the cutter-shaft. Fig.9 is a vertical central section of the same.

Paper-making machines are now very generally employed bywhich webs ofpaper of great width are producedfor instance, of a width of a hundredinches or more-such webs being cut into strips of suitable widths andsubsequently wound up into rolls. To provide a machine especiallyadapted for winding and slitting webs of paper of this description isthe object of my invention,which consists in certain novel features andcombinations of parts, as willbe hereinafter fully set forth, andspecifically pointed out'in the claims.

In the said drawings, A represents the framework of the machine, fromone end of which projects a long stud b, Fig. 4, upon which runs thedriving-pulley B, provided on one side with a conical face, which isadapted when operated by a lever, to be hereinafter described, to engagea correspondinglyshaped friction clutch-wheel C, rotating on said studand carrying a long pinion c, which meshes with and drives two gears DE, lying in dilferent planes and secured to the ends of the shafts oftwo friction winding-cylinders G H, Fig. 2, which support and rotate byfrictional contact therewith the long roll of paper K as it is cut intostrips of the desired width by rotary cutters, to be hereinafterdescribed. p

The Web of paper to be reeled up bythe friction thereon of theWinding-cylinders G H to form the roll K and cut into strips by thecutters is taken from a roll L, Figs. 1, 2,

and 5, mounted on a shaft 01, having its bearings in the framework A,the paper thence passing over a guide-roll e, under thewinding-cylinders G H, and up over the latter to the collapsible coreshaft or cylinder M, upon which it is wound up to form the roll K, the

journals at the ends of the said core-shaft fit ting within openbearings at the ends of arms 25, projecting from grooved slides f,movable vertically on guides formed at the edges of the uprights 26 ofthe framework A.

The web of paper is held against the front winding-cylinder H withsufficient friction to insure its being drawn from the roll L by arubber-covered pressure-roll 28, Fig.1 3, r0- tated by frictionalcontact with the cylinder H, the shaft of said roll 28 being supportedin journal-boxes 30, which slide horizontally in suitable guideways inthe side pieces of the framework,as shown dotted in Figsll and 2,whereby the pressure-roll is made movable toward and from the cylinderH, said'movement being eifected by an eccentric shaft 31, passingthrough slots in the sliding journalboxes 30 and having its bearings inthe sides of the framework, outside of which it is provided With anoperating hand-wheel 32, by turning which the pressure of the roll 28against the paper may be increased or diminished as desired. The roll 28prevents the wrinkling of the paper and byits action in properlydeliveringthe paper to the roll K serves to keep said roll in its properposition in contact with both of the Winding-cylinders G H.

N is the cutter-shaft, the journals of which run in hearings in lugsprojecting from a heavy cross-bar 1, extending transversely across themachine and sliding vertically on guides at the edges of the uprights26, said shaft being also supported intermediate between its ends by ahanger g, made adjustable horizontally in a slot 33 in the cross-barPand provided with a clamping-bolt and nut, as shown inFig. 3. The shaftN carries a series of thin steel circular cutters h, having theirperipheries provided with lancet-shaped teeth, as shown in Fig. 8, whichperforate the paper to the depth of a number of thicknesses. Thesecutters will produce a continuous cut as the paper is wound on the.roll-shaft M. Each of the circular cutters his secured in place upon acollar '5, being clamped between .the same and a ring 35, slipped overthe smaller portion of the collar and fastened thereto by screws 36,Figs. 8 and 9, said collars being each made adjustable longitudinallyupon the shaft N, which is provided with a spline or groove, in whichfits a block or gib j, upon which is turned a set-screw 37, passingthrough the collar, as shown in Fig. 9, the cutters bein gin this mannermade adjustable along the shaft N, so that they can be set at therequired distances apart to out the web of paper into strips ofdifferent widths, the hanger 9 being made adjustable horizontally, asbefore described, to permit of the adj ustment of the cutters adjacentthereto. The collars 2' and rings 35 bear directly upon the roll ofpaper K and by their frictional contact therewith assist in rotating thesame, causing the paper to be wound tightly upon the core-shaft, and asthese collars and rings are of less diameter than the cutters h theyserve to limit and determine the amount of penetration of their teeth asthey revolve in contact with the paper.

To one end of the cutter-shaftN is secured a driving-pulley 7s,which isdriven by an endless belt 38, passing around and receiving motion from apulley 39, which rotates on a stud projecting from the framework nearits bottom and has secured to its hub a gear 40, which meshes with andis driven by a gear 41, fixed to one end of the shaft of the rearwinding-cylinder G. The belt 38 is stretched between the pulley 39 and apulley 42 thereover, rotating on a stud projecting from a hanger 43,Fig. 3, at the top of one of the uprights 26, and passes down under anidle-pulley 44, thence around the rear side of the pulley 7c of thecutter-shaft N and over another idle-pulley 45 back to the pulley 39,the pulleys 44 45 rotating on fixed studs projecting from the oppositeends of an arm m, secured to the cross-bar P, this construction andarrangement of parts enabling the cross-bar and cutter-shaft to beraised or lowered, as required ,without varying the tension on thedriving-belt, and by thus driving the cuttershaft by means of a beltreceiving motion from one of the winding-cylinders the collars i andrings 35, which rest on the paper, are caused to rotate with the samesurface velocity as said winding-cylinders. The upper pulley 42 is madeadjustable vertically to enable the belt to be tightened if it shouldbecome slack.

To each of the slides f is secured an arm 46, carrying atits end a bar47, Fig. 3, of polygonal shape in cross-section, upon which slides agage 48, made adjustable horizontally on said bar and provided with aset-screw 49. These gages are set close up to the ends of the roll ofpaper K which is being wound up on the core-shaft M and serve to holdthe narrow trimming cut off by the two end cutters h and prevent it fromdropping off the roll until the latter is removed from the machine.

The cross-bar P is supported by means of heavy chains n, passing overpulleys g on a transverse shaft r, said chains being provided withcounterbalance-weights 50, preferably made in removable sections, thecross-barbein g raised as the diameter of the roll increases. Theseweights may be increased or diminished for the purpose of Varying thepressure of the collars and rings on the roll of paper K through themedium of the cutter-shaft N and cross-bar P, as may be found necessaryfor different grades or thicknesses of paper.

To the opposite ends of the cross-barP are secured two verticalrack-bars 51, which are engaged by pinions 52 on a shaft 53, having itsbearings in the uprights 26 and carrying a gear 54, with which meshes apinion 55 on the hub of a hand-wheel 56, by turning which the cross-barP and parts connected therewith may be raised upout of the way whenrequired to remove the roll K or commence the winding up of anew one.WVhen raised in this manner, the cross-bar is locked in place by a lever75, having a tooth 57, which engages the teeth of the pinion 55, asshown in Fig. 2, said tooth 57 being inclined on one side, so that whileit will prevent the rotation of the pinion 55 in one direction it willpermit it to rotate in the opposite direction as the bar P is raised bythe increase in the diameter of the roll K.

The heavy bar P will supply the weight necessary for tightly winding thecut strips on the core-shaft M, and therefore a cuttershaft of lessdiameter maybe used than where a cutter-shaft is employed without suchcrossbar. The cross-bar P also prevents the cutter-shaft from springing,which is very important, since some of these shafts are used on paperone hundred and fifty inches in width. If a shaft of such length was ofa diameter large enough to prevent springing the collars and cutterswould have to be correspondingly enlarged and their cost thereby greatlyincreased.

As soon as the roll of paper has attained the desired diameter thecross-bar, with the cutter-shaft is raised, and the roll is movedforward onto a table R, from which it'may be removed in any suitablemanner. The table is provided at its front edge with a guard 58 to holdthe roll in place thereon and is pivoted at 59 to enable it to be swungup intoa verticalposition as required to afford access to the cylinder Hand pressure-roll 28 when the severed end of the web is to be adjustedin place previous to attaching it to the coreshaft M to form a new roll.

I will now describe the stop-motion by which the machine is stoppedautomatically as soon as the diameter of the roll K has reached thedesired limit.

'w is a hand-lever fulcrumed at and pivoted between two lugs 61,projecting from a hollow piece or yoke 62, open at both sides, throughwhich passes the support 63 for the outer end of the pulley-stud Z2, asshown in Figs. 1 and 4E. The piece 62 is arranged to slidelongitudinally on the stud b and bears against the hub of thedriving-pulley B, being carried inward by the lever'w to force saidpulley into contact with the friction clutchwheel 0 and thereby set themachine in motion. A spring 64, Fig. 4, is introduced between the wheel0 and the hub of the pulley B to keep the latter at all times in contactwiththe sliding piece 62, so that when the lever 20 is moved outward thepulley B will be drawn back out of contact with the wheel 0, therebystopping the machine. To the lever 10 is pivoted a horizontal rod 65,the opposite end'of which slides through an opening in the framework A,between which and a collar 66 it is encircled by the spiral spring 67,which acts to throw the lever outward and disconnect the pulley from thewheel 0.-

At the upper end of the lever to is a hook g, which when the lever isforced inward by hand to start the machine engages a projection 68 onthe horizontal arm of a bell crank lever S, pivoted to the framework at69 and having its upright arm provided with a toe 70, adjustablevertically in a slot 71 by means of a bolt and nut, as shown in Fig. 7.To the cross-bar P is pivoted a bell-crank tappet '72, the vertical armof which takes a bearing against the cross-bar, as shown dotted in Fig.1, while its horizontal arm projects outward into a position to strikethe inclined side of the projection 70 when the crossbar P has beencarried upward to the desired height by the roll of paper K, thusoperating the lever S and tripping the lever 20, which is then actuatedby the spring 67, when the pulley B will be moved by the spring 64 outof contact with the wheel 0, causing the machine to instantly stop asdesired.

To vary the diameter of the roll K and consequently the quantity ofpaper reeled upon the core-shaft M, it is merely necessary to adjust thetoe 70 in the slot 71 of the lever S to release the stop-motion at thedesired time, and I am thus enabled to make any desired number of rollsof uniform size without requiring any care or attention on the part ofthe operator.

When the cross-bar P is raised to its full height, the tappet 72 will beabove the toe 70, and on the descent of the bar P it will turn upward onits pivot, as is necessary to allow it to slip past said toe.
